I've run into a problem with resuming a suspended VM from an iSCSI disk. I made an iSCSI target on my NAS device and used it as a physical disk to install VM (Windows 8 Pro x64) onto. Everything went smoothly and I did not encounter any problem at that time.
Few days later, I tried to resume the suspended VM, but VMware Workstation always fails now with an error "The physical disk is already in use". iSCSI disk is connected via built-in Microsoft iSCSI initiator and is not mounted in the host operating system (no drive letter assigned) - see attachment.
Task Manager in Windows indicates no activity on the disk. I've tried to disable antivirus/firewall (ESET Smart Security) but that did not help either. I'm desperate and totally clueless what might be causing the problem. If any of you could provide a hint or suggest a solution, I would be really grateful, as it took me some time to setup the guest OS. Thank you very much.
VMware Workstation 9.0.3
Host OS: Windows 8.1 Pro, 64-bit (Build 9200) 6.2.9200
Guest OS: Windows 8 Pro
